雷达传感与异步收发机通信的集成

Integration of Radar Sensing into Communications with Asynchronous Transceivers

J. Andrew Zhang, Kai Wu, Xiaojing Huang, Y. Jay Guo, Daqing Zhang, Robert W. Heath

摘要:

在将雷达传感集成到通信网络中时,时钟同步是一个关键问题。它可能会导致测距模糊,并阻止与异步收发器集成的不连续测量的相干处理。如果它被解决,传感可以在通信网络中有效地实现,需要很少的网络基础设施和硬件变化。本文提供了一个系统的概述现有的和潜在的新技术来解决这个基本问题。我们首先回顾现有的解决方案,包括使用微调的全局参考时钟,基于单节点和基于网络的技术。然后,我们研究开放的问题和研究机会,提供洞察力,在三个解决方案领域的每一个可以更好地实现。

英文摘要:

Clock asynchronism is a critical issue in integrating radar sensing into communication networks. It can cause ranging ambiguity and prevent coherent processing of dis-continuous measurements in integration with asynchronous transceivers. Should it be resolved, sensing can be efficiently realized in communication networks, requiring little network infrastructure and hardware changes. This article provides a systematic overview of existing and potential new techniques for tackling this fundamental problem. We first review existing solutions, including using a fine-tuned global reference clock, and single-node-based and network-based techniques. We then examine open problems and research opportunities, offering insights into what may be better realized in each of the three solution areas.
